ROLLER-SKATE.

Specification of Letters Patent.

Patented Nov.1'2, 1912.

Application filed August 14, 1911. Serial No. 644,019.

Toall whom it may concern:

Be it known that I, THOMAS E. KING, a citizen of the United States,residing at Stockton, in the county of San Joaquin and State ofCalifornia, have invented a new and useful Roller-Skate, of which thefollowing is a specification.

This invention relates to roller skates and has for its object toprovide an improved,; substantial and cheap device of this chari in thesocket 11.. The horizontal arms 24 of acter.

means for changing the alinement of the rollers according to theshifting of the.

With the above ends in view this inven-;

tion is embodied in certaindetails of construction which are hereinafter"described and pointed out in the appended claims.

The invention is illustrated in the accompanying drawings, in WhlCh.similar reference characters indicate similar parts, and

ably stamped and pressed from sheet metal.

v at each end of the skate, each being of L-,

To strengthenthis foot plate has been provided a casting, preferably ofwrought iron, comprising an elongated block 7- and an upper flange 6,which flange is riveted to the bottom of the foot plate 5, the castingextending from the heel' portion of the foot plate to the toeportion'thereof. The ends of the block 7 are reduced'indepth asindicated at 10 and have the lower faces thereof declined outwardlytoward the end of the skate. In each end 10 of the block is arranged avertical hole or socket 11.

A vertically arranged stud bolt 21 having the lower head 20 is screwedinto each end of the deeper portion of they block 7 and a jam nut 19 oneach of the said bolts serves to hold same: in position by bindingagainst the said block 7. A carrier 14 is arranged A further object isto provide improvedshape comprising a vertical arm 13 and ahor1zonta1'arm 24. A pint-1e 12 projects from each of the vertical arms13 .an enters .the respective sockets 11 in the reduced ends 10 of theblock 7 to form a swivel connection between the carriers and the saidblock. The axis of each of the intles 12 and the corresponding. socket11 intersects the axis of the corresponding bolt 21 at a point below thefloor, and the pintles 12 are slidable axially the carriers have anintegral cup 16 at the outerends thereof and a sleeve 23 integraltherewith intermediate the ends thereof.

The cupped ends of the arms 24 are mounted loosely on the respectivebolts 21 and normally rest onthe heads 20 of the said bolts.

ends of the arms 24 of the carriers throw a greater portion of theweight of the skater,

on the cushion 17, which being resilient obviates the jarring caused bythe movement of the skate over the surface of the floor.

Upon the weight of the skater shifting to the carriers will swing aboutthe axes of the pintles 12, which will cause the cup-shaped portions 16which loosely engage the bolts 21 to move at a greater rate of motionthan the lower ends of the bolts, or causing the cup-shaped portions 16.to move laterally and upw'ardlyrelative to the bolts as the bolts areswung. It will therefore be noted that when the foot plate is sloped toa proper angle, that the bolts 21 will strike the cup-shaped portions 16for the purpose ed loosely on the bolts 21 and embedded in v of limitingthe tilting movement of the foot plate. The lateral motion of thecup-shaped portions 16 relative to the bolts also causes the cushions 17to be bowed or twisted in order to impede the tilting movement of thefoot plate and in order to retain the wheels in alinement unless theproper pressure is applied to the foot plate to tilt same. It 10.

is for this reason that the cup-sha%ed' portions 16 are mounted looselyon the olts 21, and that the tubular cushions 17 are mountthe respectivecup-shaped portions 16 and the cups 18. As shown in Fig. 3, the diam- Yeter of the bolt 21 is smaller than the opening in the cup-shapedportion 16 and the I passage through the cushions in order to permit theoperation of the devices above described.

.Each end of the block 7 and each of the carriers 14 and correspondingparts are of like design and proportions whereby the parts at the twoends of the skate are interchangeable and being similar dispenses withthe necessity of having two carriers of different design andconstruction. a The block 7 extending from the toe portion of the skateto the heel portion thereof strengthens that portion of the foot plateintermediate the heel and toe which has been found to be the weakestpoint thereof and which has .otal and slidable engagement with the footplate on an axis which intersects the axis of the said member below thefloor, wheels carried by the carrier, and a cushion on the said memberbetween the foot plate and the carrier, whereby when the foot plateistilted sidewise the carrier moves laterally at its point of engagementwith the said member at a greater rate of motion than the said member atthat point in order to impede and limit the tilting movement of the footplate.

2. In a roller skate, a foot plate, a member dependingtherefrom andhaving a lower head, an L-shaped carrier having its horizontal'armloosely engagin the said member and having its vertica arm pivotallyand slidably engaged" to the foot plate on an axis which intersects theaxis of the said member below the floor, wheels'carried b the carrier,and a tubular cushion dispose between the foot plate and'the horizontalarm of the carrier, so that when. the foot plate is tilted sidewisethehorizontal arm of the carrier moves laterally at its point of engagementwith the said member ata greater rate of motion than the said member atthat point in orderto ede and limit the tilting movement of the cotplate.

. v v 3. In a roller skate, a foot'plate, a member secured on the bottomof the foot plate and having a socket therein, a bolt screw-threadedinto the said member and having a lower head, an inverted cup on theupper end of the bolt, an L-shaped carrier, the vertical arm on thecarrier having a pintleengaging slidably in the said socket, the. axisof the socket and in tle intersecting the axis of the bolt at a pointbelow the floor, and the horizontal arm of the carrier having acupshaped end loosely engaging the bolt, a tubular cushion having theends thereof embedded in the said cup and cup-shaped end of thehorizontal arm, and wheels carried by, the said horizontal arm, so thatwhen the foot plate is tilted sidewise the said cupshaped end moveslaterally at a reater rate of motion than the lower end 0 the bolt inorder to impede and limit the tilting movement of the foot plate.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
